About our new build mastic in South Portobello
A new build should have a neat, sound bead at every joint. When the finish is smeared, patchy or already cracking, it’s worth putting right early, before water gets into the floor or walls. We work on windows & doors, bathrooms & en suites and show homes, and the jobs we see most are gaps opening as the house dries out and settles and gaps behind new kitchen upstands.
Older tenement flats usually have timber floors on joists, with skirting joints that open and close with the seasons. For a flat in South Portobello, a flexible sealant copes with that movement where filler would crack.
Every job is covered by a one-year guarantee, wherever you are in Edinburgh.

In a tenement flat in South Portobello, a failed seal is rarely just your problem: water can reach the flat below, and gaps in shared walls or fire-stopping affect the whole stair.

Surface by surface
Bathrooms and en suites
New-build bathrooms and en suites are where sealant fails most often. We cut out the failed bead, clean and prime, and reseal with anti-fungal sanitary silicone.
Skirting and floors
Where the floor meets a bath panel or kitchen plinth, the joint keeps mop water out. They get a flexible, water-resistant sealant.
Landlords, agents and businesses in South Portobello
Businesses can book us for washrooms, kitchens, offices and more. For commercial premises, we can talk through working times when we quote.
We work for landlords and letting agents as well as householders. Resealing between tenancies keeps a property looking cared for.
What happens on the day
When we arrive, we start by going over the job with you, so you know exactly what we’re doing. We protect the surfaces around the joints before work begins. The work normally takes anything from a few hours to several days, depending on the number of plots. In a Scottish city, a lot of jobs are in tenement flats, up a common stair from a shared close. In South Portobello, it helps to know the floor, the door entry arrangements and the nearest parking.

- We cut out every bit of the failed or messy sealant.
- Each joint is cleaned of dust and grit, then primed if required.

Advice
DIY sealant or a professional job?
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.
The biggest DIY mistake is sealing over old sealant. New silicone will not bond to old, so it lifts and traps water and mould underneath. All the old material has to come out first.
How to look after the new joints
Joint life depends on how it’s used and looked after. We suggest:
- Wipe joints with warm soapy water
- Avoid running a DIY bead over the old one
- Ventilate bathrooms well, especially in the first year
- Report sealant problems to your builder during the snagging period
Ventilation matters in a new home, which is still drying out. Run the fan or open a window after bathing so moisture does not sit on the sealant.
A seal that splits early is often a sign of movement. Have it resealed, and the tray or bath checked, before it gets worse.
